RAILROAD STOCK-G UARD.

SPECIFICATION forming part of Letters Patent No. 585,548, dated June 29, 1897.

Application filed December 5, 1896- $erial No. 614,664. (No model.) i

To all whom, it may concern.-

Be it known that I, THOMAS JEFFERSON AL- LEN, a citizen of the United States of America, residing at Pleasant View, in the county of \Vhitley, in the State of Kentucky, have invented certain new and useful Improvements in Railroad Stock-Guards; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference to be had to the accompanying drawings and letters of reference made thereon.

The object of this invention is to provide a guard which will prevent live stock passing along the track into an inclosure, the said guard practically forming a continuance of a fence which ends adjoining the tracks.

The invention embodies a series of rollers or guards placed parallel with the rails of the railroad and having serrated edges, by which the animal attempting to pass over the said guard will turn the rollers and cause the points to contact with his ankle or lower part of his leg. With the above ends in view my invention consists in the particular construction of the said rollers and manner of attaching them to the cross-ties by which they extend parallel with the tracks.

In the accompanying drawings, forming part of this specification, Figure l is a perspective view of a stock-guard constructed in accordance with my invention, showing a por tion of one end of the rotatable rollers or guards. Fig. 2 is a perspective view illustrating the manner of assembling the plates which make up the rollers or guards. Fig. 3 is a perspective view of one of the stub-axles which are connected to the ends of the rollers or guards.

The rollers or guards are each made up of a number of plates, the outer edges of which are serrated or provided with teeth a. The plate I) is straight or flat, while the other plates are bent to form a loop U -shaped in cross-section having a straight connecting portion 0. These plates are assembled so that the connecting portion 0 of the angle-plates will bear on each side of the intermediate portion of the flat or straight plate, transverse apertures or holes being provided by which the said plates will be held securely together in the manner hereinafter set forth.

d designates a bar the outer end of which is reduced to provide a cylindrical bearing or stub-shaft f, the other end of said bar being bifurcated to present members which will embrace the several plates hereinbefore described and bear against the connecting portion 0 of the angle-plates, the said members being provided with apertures or holes, which register with the apertures or holes in the plates, and through these holes are passed bolts for rigidly connecting the parts. The opposite end of the guard or rollers is provided with a similar bar to present a stubshaft.

Brackets or angle-plates h are provided to form bearings for the rollers, and said angleplates are secured to the cross-ties of the railroad by screws which pass through slots 2' therein. These angle-plates h are ranged longitudinally to the ties, and those located between the tracks are of such length as to support the rollers at this point, and those beyond the tracks are preferably of a length sufficient to bring the outer rollers adjoining the end of the fence. The intermediate portion of the rollers are provided with bolts which pass through all of the plates that form said rollers.

Rollers or guards constructed to present serrated edges or teeth act more efiectually to prevent an animal passing over than were said teeth dispensed with and the edges made straight or plain. I have also designed a particular construction by which these rollers can be cheaply made, and by arranging them parallel with the tracks they are more efiective than if arranged crosswise. It will be understood, of course, that the rollers or guards are placed a slight distance apart, so that when the animal treads upon the plates or blades the rollers would be turned to bring the adj'acent plates or blades in contact with the ankle or leg of the animal.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination in stock-guards for railroads, of the brackets or angle-plates secured to the ties and arranged lengthwise thereon, rollers or guards made up of plates having serrated edges, and bifurcated bars securing the plates together at their ends and forming stub-axles, substantially as shown and for the purpose set forth.

2. Aroller for stock-guards, made up of flat 5 plate I) and angle-plates c substantially U- shaped in cross-section, such plates being assembled by placing the angle-plates on opposite sides of the straight plates; together with bars cl bifurcated at one end to present mem- IO bers Which embrace the aforesaid plates, the
